I expect that your code is about 10 lines long.
Can you please post it?
Between the time of originally posting and now, I changed the length of
the vector and now am able to see a decent received signal.
The relevant code:
src_data = (0,)*800 + (1,)*800
vectordata = gr.vector_source_c(src_data, True)
multiplier = gr.multiply_cc ()
self.connect (adder, (multiplier, 0))
self.connect (vectordata, (multiplier, 1))
self.connect (multiplier, self.u)
adder is gr.sig_source_c(2000000, gr.GR_SIN_WAVE, 20000, 1000, 0).
self.u is the usrp sink.
Now the amplitude of the sine wave appears modulated but it looks like the
frequency changes slightly which might make demodulating hard(?).
